#vulnerability

### Impact A vulnerability in Ghost's handling of Staff Token authentication allowed certain endpoints to be accessed that were only intended to be accessible via Staff Session authentication. External systems that have been authenticated via Staff Tokens for Admin/Owner-role users would have had access to these endpoints. ### Vulnerable versions This vulnerability is present in Ghost v5.121.0 to v5.130.5 to and Ghost v6.0.0 to v6.10.3. ### Patches v5.130.6 and v6.11.0 contain a fix for this issue. ### References Ghost thanks Sho Odagiri of GMO Cybersecurity by Ierae, Inc. for discovering and disclosing this vulnerability responsibly. ### For more information If there are any questions or comments about this advisory, email Ghost at [security@ghost.org](mailto:security@ghost.org).

### Impact A vulnerability in Ghost's 2FA mechanism allows staff users to skip email 2FA. ### Vulnerable versions This vulnerability is present in Ghost v5.105.0 to v5.130.5 to and Ghost v6.0.0 to v6.10.3. ### Patches v5.130.6 and v6.11.0 contain a fix for this issue. ### References Ghost thanks Sho Odagiri of GMO Cybersecurity by Ierae, Inc. for discovering and disclosing this vulnerability responsibly. ### For more information If there are any questions or comments about this advisory, email Ghost at [security@ghost.org](mailto:security@ghost.org).

### Summary An Unauthenticated Insecure Direct Object Reference (IDOR) vulnerability was identified that allows an unauthenticated attacker to access guest address information without supplying valid credentials or session cookies. ### Details During testing, it was observed that all guest users can make an unauthenticated request to retrieve address data belonging to other guest users by manipulating object identifiers. The attacker would need to know the storefront URL structure to perform this attack (which can be learnt after creating a registered user account). Affected Component(s) * Address Edit endpoint: `/addresses/{addressId}/edit` Root Cause - Faulty authorization check in CanCanCan Ability class: ```diff - can :manage, ::Spree::Address, user_id: user.id + can :manage, ::Spree::Address, user_id: user.id if user.persisted? ``` the `user` object in `Spree::Ability` class for guest users is a `Spree.user_class.new` object. Addresses endpoint to access it is part of the `...

### Summary An Authenticated Insecure Direct Object Reference (IDOR) vulnerability was identified that allows an authenticated user to retrieve other users’ address information by modifying an existing order. By editing an order they legitimately own and manipulating address identifiers in the request, the backend server accepts and processes references to addresses belonging to other users, subsequently associating those addresses with the attacker’s order and returning them in the response. ### Details Affected Component(s) - Authenticated user order management - Address association logic - Order update endpoint(s) Affected Endpoint(s): - `/api/v2/storefront/checkout` The application fails to enforce proper object-level authorization when updating an existing order. While the user is authenticated and authorized to modify their own order, the backend does not verify that the supplied address identifiers belong to the same authenticated user. ### PoC Preconditions - Valid authentic...

# Summary The function `list_html` generates an file view of a folder which includes a render of the current path, in which its inserted in the HTML without proper sanitation, leading to reflected XSS. The request path is decoded and normalized in the matching stage but is not inserted raw in the HTML view (current.path). The only constraint here is for the root path (e.g., /files in the PoC example) to have a subdirectory (e. g., common ones like styles/scripts/etc.) so that the matching returns the list HTML page instead of the Not Found page. # Details The vulnerable snippet of code is the following: [**dir.rs**](https://github.com/salvo-rs/salvo/blob/16efeba312a274739606ce76366d921768628654/crates/serve-static/src/dir.rs#L593) ```rust // ... fn list_html(... let mut ftxt = format!( r#"<!DOCTYPE html><html><head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width"> <title>{}</title> <style>{}</style></head><body><...

A XSS vulnerability exists in in React Router's `<ScrollRestoration>` API in [Framework Mode](https://reactrouter.com/start/modes#framework) when using the `getKey`/`storageKey` props during Server-Side Rendering which could allow arbitrary JavaScript execution during SSR if untrusted content is used to generate the keys. > [!NOTE] > This does not impact applications if developers have [disabled server-side rendering](https://reactrouter.com/how-to/spa) in Framework Mode, or if they are using [Declarative Mode](https://reactrouter.com/start/modes#declarative) (`<BrowserRouter>`) or [Data Mode](https://reactrouter.com/start/modes#data) (`createBrowserRouter`/`<RouterProvider>`).

### TL;DR This vulnerability affects all Kirby sites where user permissions are configured to prevent specific role(s) from performing write actions, specifically by disabling the `update` permission with the intent to prevent modifications to site content. If developers haven't configured any user permissions that deviate from the default of allowing all actions, their site is *not* affected. ---- ### Introduction Kirby allows to restrict the permissions of specific user roles. Users of that role can only perform permitted actions. Permissions for updating content have already existed and could be configured for each model type, but were not enforced by Kirby's API backend code during operations to the changes version. The changes version is the content version that contains unsaved changes of existing models (pages, users, files or the site). ### Impact The missing permission checks allowed attackers with Panel access to create or discard a changes version or update the cont...

Multiple CoreDNS server implementations (gRPC, HTTPS, and HTTP/3) lack critical resource-limiting controls. An unauthenticated remote attacker can exhaust memory and degrade or crash the server by opening many concurrent connections, streams, or sending oversized request bodies. The issue is similar in nature to CVE-2025-47950 (QUIC DoS) but affects additional server types that do not enforce connection limits, stream limits, or message size constraints. ### Impact #### 1. Missing connection and stream limits (gRPC / HTTPS / HTTP3) The affected servers do not enforce reasonable upper bounds on concurrent connections or active streams. An attacker can: - Open many parallel connections - Rapidly issue requests without limit - Consume memory until the CoreDNS process becomes unresponsive or is terminated by the OOM killer Testing demonstrates that modest resource configurations (e.g., 256 MB RAM) can be exhausted quickly. Increasing concurrency parameters in the PoCs allows attackers...

### Summary An unsafe implementation in the `click` event listener used by `ui.sub_pages`, combined with attacker-controlled link rendering on the page, causes an XSS when the user actively clicks on the link. ### Details 1. On `click`, eventually `sub_pages_navigate` event is emitted. https://github.com/zauberzeug/nicegui/blob/59fa9424c470f1b12c5d368985fa36e21fda706b/nicegui/elements/sub_pages.js#L41-L63 2. SubPagesRouter (used by ui.sub_pages), lisnening on `sub_pages_navigate`, `_handle_navigate` runs. https://github.com/zauberzeug/nicegui/blob/59fa9424c470f1b12c5d368985fa36e21fda706b/nicegui/sub_pages_router.py#L18-L22 3. `_handle_navigate` runs `run_javascript` with f-string substituting `self.current_path` which is simply surrounded by double-quotes. The string context can be broken out easily. https://github.com/zauberzeug/nicegui/blob/59fa9424c470f1b12c5d368985fa36e21fda706b/nicegui/sub_pages_router.py#L73-L88 ### PoC The minimal PoC boils down to this: ```py from ni...
